Aspheres Extreme Precision Aspheric Optics

Precision aspheres are manufactured with extreme
precision aspherical manufacturing technologies.

In the digital age, aspheres are growing in popularity in modern optical lens designs. Aspheric surfaces can now be found in most IR designs, and are increasingly prevalent in the visible and DUV spectrum for a range of consumer, defense , medical and semiconductor applications. High end aspheric surfaces are also increasingly critical in lithography lenses.

Zygo's Extreme Precision Optics Group in Richmond, California, fabricates world-class aspheres and ultra-high precision aspherical optical assemblies, serving the Defense & Aerospace, Life Sciences, and Semiconductor markets.
